Box-MAKING MAci-inv easis To all'whomc'tmag concern? i Be it known'that 1,;Gnonon A. Cox, a citizen of the United States, residing 1 at Brewsten'in the county of ()lranogan and Stateof""Washington, have invented certain new" and useful Improvements in Box- Making Machines, of which the following is a specification. i i f I The present invention relatesto certain new and usefulimprovements in box male.

ing niacliines, andhas for its object to pro I verse sectional view on the line 3-3'0fl3ig. 1. Fig. at is alongitudinal sectional V16? videaldevice ofthis character which embodies no'vel features'of construction where-.; by packing boxes may be rap dly assembled and nailed together, thereby enabling such boxes to be manufactured in large quantities at a comparatively small cost.

Further objectsof the invention are is bottom of abox to be quickly'and accurately nailed to the QIlClPlBCQS thereof, and which comprises few and durable parts such as are not liable to get out of adjustment or repair. I

With these and other objectsin view, the

invention consists incertain novel combinations and arrangeinentsof theparts as will more fully appear as the description proceeds, the novel features thereof being point- 1 ed out in the appended claims.

For a full understanding of which Figural isa front elevation of a box inalrv ing machine constructed in accordance with.

the invention, a partly completed box be ing' shown as clamped between the cla1np-' ing heads thereof by dotted lines. Fig. 2 is a top plan view thereof. Fig. 3 is atransthrough one of the clamping heads taken on the line 1: of Fig. 2. Fig. 5 is a transverse sectional view'talfen'on the line 5'-5 of Fig.4.

. Corresponding to in the following description-and ind cated in all't'heviews of the drawings by the same reference characters.

Referrin to the drawin s which illus trate one embodiment of the invention, the

reference character A designates the stand,

and at the rear :of the-stand thereis pro-- V vided a superstriicture fl .wlii clibsupports amaterial shelffd. Suitable boards for forniing the ends and sides'of thefboxes are placed upon the. shelf 4 so that they are:

within convenient reach of tlie'operator and; I

can-be quickly removed from the shelfas lower end thereof by a transverse bar 6. If desired, suitable'ledges of shelves 7 may be applied to. opposite'end portions of the stand A at the front thereof.

Mounted upon the stand A is a swinging frame B, said frame including a horizon.-

tally disposed and longitudinally extending" back piece .8 l which is 'hinged at9 to the rear of the stand A so as to be susceptible of being tilted or swung about a horizontal axis. Projectingforwardlyfrom the back piece Sare three pairs of arms 1-0 which are provided with suitable bearings within which the shafts'11,12 and 13 are journaled, said shafts being horizontally disposed and ar anged in alinem'ent; with each other.

At opposite ends of the swinging framenB diagon'al braces Hare applied tothe tops of the arn'is '10 and'back pieces Sso as" to reinforce the said arms and holdthem rigidly a reinforcing strin15 is applied to the lower faces of the arms 10 and extends longitudinally ofthe niachine, theiniddle portion of the strip 15 being connected by a pitman 16' to a su table treadle mechanism (1, by means" of whichthe frame B can be swung up and J down.

sliding movement within "their respectivem clamping" heads 17 which, as illustrated by bearings; The adjacent ends ofv the several shafts 1'1, 12 and 13 are provided with 1 H Fig. 1, are adapted to gr p boxends X which" rest upon the'sills 5 and are arranged'in an in position. It will also be observed that box can be applied to uprigh position. The shaft 13 isprovid d with a set collar 18 which engages one of the arms 10' to limit the sliding, movement of the said shaft toward the right hand end of the machine. The opposite end shaft 11 is provided with aset collar 19 which provides an abutment a loose collar 20, said loose collar being adaoted to be engaged by a cam lever'ill for the purpose of forcibly movin the shaft 11 toward the ri 'ht hand upon each of the shafts 11 and 13, being arranged adjacent to the clamping heads 17 of the said shafts; and being shown as provided with peripheral flanges which extend over the edges of the said clamping head weights 2% appl that after being rotated through partial revolution the drums will return to their original positions by the action of gravity. Each of the drums 22 is also provided'with a pawl 25 which is held in a yielding engagement with a ratchet wheel 26 upon the adjacent clamping head 17 by means of a spring 2?. It will thus be obvious that when the drums 22 are rotated in one direction the pawls 25 will interlock with the ratchet wheels 26 to produce a corresponding rota-- tion of theshafts 11 and 13, although when the drums are rotated in a reverse direction the spring actuated pawls "rill slip over the teeth of the ratchet wheels 26. i

A flexible strap or cable 28 is secured to the exterior of each of the drums 22 at a suitable point on the periphery thereof as indicated at said straps being also connected at sale the stand AL When the frame l3 isswung upwardly by the action of the treadle moch m U, the straps 9-8 unwind from the per heries of the drums 22' and produce a rot The pawls 25 coop wheels 26 during te with the ratchet movement to rotate the shafts l1 and 13 for a quarter revolution. Thebox ends which are clamped between the clamping heads 17 will also be rotated a quarterrevoluti n, with the result that the side i which was previously nailed to the box end X will be swim toward the front of the machine and the box ends brought into position for This operation is re-.

ailing another side thereto. peated untllvthe two sides and bottom have been successively nailed to the ends. The

These drums are providedwith d to-one side thereof so.

cam lever 21 is then moved into inoperative position so as to release the box and permit the same to be removed from the machine. A fresh set of box ends may now be inserted between th clamping heads 17 and the operation repeated, the proper rotation of the box heads for a quarter revolution each time the treadle mechanism'is operated enabling the sides to be veryquickly and accurately nailed to the ends so that a single operator can assembl and nail a largenumber of boxes in a short period of time.

The treadle mechanism C includes a reel: shaft 31"which is ournaled between the transverse bars 6 at the bottom of he stand A and extends longitudinally of the machine. Projecting rearwardly from the 111i dle of the rock shaft 81 is an arm 32 which is pivotally connected to the pitman 16. in a similar manner a foot piece 33 projects forwardly from one end of the rock shaft 31 so that it can be readily depressed by the footof the operator. Upon depressing this foot piece 33 the frame 13 is swung upwardly together with the box ends X which may be 'will be rotated by the weights 24 so as to a ain wind the straps 28 upon the peripl1- eries thereof. The machine requires but very little attention from the operator and with its assistance a single man can assemble and nail a large number of boxes in a short period of time and at comparatively small cost. The machine is more particularly intended for use in the manufacture of those boxes which are used in enormous quantities for-the packing of fruit in those parts of the country where fruit growing is one of the important industries, although the machine can also be used for manufacturing packing boxes for any purpose.
